    I am planning to build a 32' x 6' x 2' flat bottomed steel hulled sternwheel steamboat to be used only in rivers. Am wondering what gauge of metal to use on bottom and sides. Wanting to keep it light as possible.

    Welcome to the forum.

    You do realize that's an imposable to answer question right? Scantlings are based on loading and weights. Have you performed a weight study? What steel build method will you be using (yep, there's more then one)? Keeping her light is a wise thing, but without a lot more information about the design, it's parameters and hydrostatics, any suggestions would just be a guess.

    As PAR said, welcome to the forum. The thickness of the plating is determined in conjunction with the number and size of the frames. More frames will allow for thinner plating. But to find out what these sizes are is determined by an proper engineering approach. There are lots of calculations to do and iterations to make to arrive at the best solution. You should consult a naval architect and/or experienced boatbuilder for further advice. A simple answer cannot be given in a forum such as this.
